This is a utility to help with the testing of TCP server software.

It exports a single subroutine get-unused-port that will return a port number in the range 1025 - 65535 (or a specified range as an argument,) that is free to be used by a listening socket. It checks by attempting to listen on a random port on the range until it finds one that is not already bound.
